Spondylolisthesis

The term ‘Spondylolisthesis’ refers to a condition where a vertebra has moved out of alignment relative to the one below and is often described as a ‘slip’. The causes are varied; some occur in adolescence from stress reactions while others result from degeneration (arthritis) later in life. Surgery is considered when the spondylolisthesis becomes progressively larger or when it results in pressure on nearby spinal nerves.
